An experiment is conducted to determine how the arm length of a pendulum effects its period. the experimental design calls for varying the length of the arm and the mass of the bob. which is true about this experiment, based on good experimental design? a. only the arm length should be changed. the mass should remain the same. b. the force applied to the mass should be varied for trial. c. the material the arm is made of should be varied for each trial. d. only the mass should be changed. the arm length should remain the same

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
